Parker Hannifin, original Patent Holder (US 6851729 B2), for "Tube Fitting, Medium Pressure" developed the MPI Medium Pressure compression fitting connections to be secure and gas-tight while being made manually (wrench turns) or hydraulic set tool. This connection has application throughout industry, including off-shore oil and gas exploration platforms, research labs, and other facilities that require operating pressures to 15,000 psi (1035 bar).

MPI™ Fittings are ideally suited to handle liquids, gases, or chemicals and can be used on a wide variety of tubing materials including: Instrument Grade thick-walled annealed 316 SS, 1/8th Hard (cold drawn) 316 or 317 SS MPI tubing, and 2507 Super Duplex MPI tubing up to 1" OD. Every Parker MPI™ Fitting is supplied complete with both ferrules and compression gland nut, ready to install.

NOTE:
  • Replace "SS" with "2507" for Super Duplex
  • Assemble 1/2 turn from finger tight.
  • Dimensions in inches are for reference only, subject to change.
  • Pressure Rating of Fittings is controlled by tubing selected and choice of ASME Standard.
  • -XF Ferrules are required for 3/4" and 1" 316 SS or 2507 Super Duplex Tubing.

    Specifications

    Features

    		 N/A Every MPI™ Fitting has the features shown below:
    1. Front ferrule with corrosion-resistant Parker Suparcase® forms a seal between the tube, body and ferrule. It also provides a mechanical hold on the tube.
    2. Back ferrule with corrosion-resistant Parker Suparcase® provides a strong mechanical hold on the tube.
    3. Longer thread area for improved resistance to pressure and load on the ferrules.
    4. Molybdenum disulfide-coated inverted nut helps prevent galling, provides easier assembly, and permits multiple remakes.
    5. Long tube-support area improves resistance to vibration and line loads.

    Materials and Identification

    		 N/A Standard MPI™ Fittings and Valves are made of Heat Code Traceable 316 SS or optional 2507 Super Duplex materials. Tubing and fitting materials should be selected based on compatibility with the fluid or gas media.

    Part numbers for MPI™ Fittings use symbols that identify their style, size, and composition. 2507 material is easily identified by a groove in the gland nut hex.

    Engineering Standards Used

    		 N/A Parker Hannifin has designed all fittings and valves using the following ASME Standards and associated Safety Factors:

    ASME B31.1 Power Piping
    ASME B31.3 Process Piping

    Assembly

    		 N/A MPI™ Fittings are assembled with standard hand tools up to 3/4" size. 1-1/2 turns past finger tight is all that is needed, 3/4 and 1 inch 316 SS tubing and 3/4 and 1 inch 2507 Tubing must be hydraulically preset. Note: All sizes can be hydraulically preset using the Parker Preset Tooling.
